Specification of Letters Patent.

Application-filed'September 4, 1912. Serial Noft'lfiflfll.

To allabhom it-may concern he 1 it lmqwn that l, Cumulus Porn, a resident of Pittsburgh, Pennsylvania, have invented certain -new and useful Improvee ments in Apparatus for Baking Plates and otherJUses, of which the-following is a specificauionyeaccompanied-by -dra'win'gs.

The apparatus is particulariy designed forJexpos'ing plates -laoquered on both sides 10 tohternperature and oarry-ing them ,wh.i -le-;supported upen small orsharp supportslthnoughithe baking chamber, butit 1s also applicable to carrying tubes and other bodiesgas will hei'presently understood.

kltlis desirable to reueivetheplates or other articlesfrom the ,coating devices in such a way andmonarny them iii-such a way through the rover; .thatlthe coating shall not become scratched .or injured and that no considerable-area shall-he incontaet with the suprte.

,present invention in its best form provides means for receiving and-carrying the articles through-the oven upon sharp su ports, some for: all of which can yield and adg' ust "themselves in :reoeiving the coated articles so.as,not .to scratch or substantially in'ure-the coating.

.1 many respects the present invention so forms an improvement upon apparatusmore broadly claimed in my pending application filed August -7th,.-19 1 2 Number 713,795.

:In thedrawings,Figure 1 is a side'view, partly diagrammatic, showing a baking oven, conveying apparatus and coating rolls enibodying the present invention; Fig. 2 is a detail view of certain features of the conveying apparatus; Fig. 3 is=ano'ther detail view; Fig. 4 is a view of another embodi- 4o nrent .ofathe inventien; Fig. 5 is a view of certain details of another form of the invention; Fig. 6 is a side view of Fig. 5, partly in section; and Fig. 7 is a horizontal section on the line 7-7 of Fig. 6.

In the drawings, Fig. 1 shows a baking oven 10, through which runs an endless conveyer, the conveying device 1101 which passes around the sprocket wheels 12 and 13 at either end and is suitably supported with- 63s in the oven 10. At 14 are diagrammati cally shown the coating and delivering rolls of apparatus for coating plates 15 with lacquer on both sides and delivering the same to the conveyor 11. For carrying plates in horizontal position through the oven, this ,conveyer has preferably the details of construction shown in Figs. 2 and 3. To-each of the cross bars 20 secured to the chainsof the conveyor 11 is detachably fastened -a removable carrier21 provided with a row of spiral resilient pin supports '25, which are-preferablysubstantially sharp at their upper supporting end and are screwthreaded into-the carriers 21. These carriers 21 are conveniently fastened to the cross bars-20 by the winged screws 22. The yielding sharp pin supports 25 are set so that their supporting pointslie in a com- 1non. pl;ane in the upper side of the conveyer, as Willbe clear from Figs. 1 and 2, and receive the lacquered plates, which should, of course, lee-passed on to them from the rolls 14 at the same speed at which-the conveyer travels. *ConSequently, if the'reis any slight movement between the plates'15 and the pin supports 25, thel-atter can yield and automatieallyadjus't themselves so as to permit such slight-movement of the-plates without scrapingor scratching the lacquered surface If thepin supports 25 becomeclogged with lacquer so as to-need cleaning, or if it is desired to'removethem for any other purpose, the entire carrier 21 can be taken ed as a unit and readily replaced.

In Fig. 4, carriers 121 sliding and secured in an undercut groove 127 in-the cross bar 120-are shown, further secured by a winged set screw 122, if desired.

Obviously also; other variations of the invention mayreadily be made.

In -Figs. 5, 6 and 7, provision is made for receiving and'supporting the plates 15 upon one edge-ina nearly verticalposition. Each cross bar 220 of the conveyor is, in this form,

provided with two upright carriers 221 fitting into dovetail slots 227 in the cross bar 220, and tightly held, if need be, by the winged set screws 222. Each of these carriers is provided toward its lower end with knife edges 225 meeting in a ii-shaped notch for receiving the extreme lower edge of the plate without injuring the surface of the plate. Toward the upper end, each carrier 225 is provided with a yielding pin support 25, like those already described. With this form of the improvement, the plates 15 are delivered downward from above, and as their lower edges reach the notch between the edges 225, the upper portion of the plate is allowed to fall or come against the pin Patented Jan. 5, 1 .915.

supports 25, which, as before described, i

yield sufiiciently to adjust themselves withoutscratching the lacquered surface.

It will be seen that the invention not only provides means for receiving the articles and allowing the points of support to adjust themselves slightly in the act of receiving, but also provides ample adjustment of the supports for the expansive movements of the plates or other articles under the heating efiects of the oven. Also, the resilience of the supports tends to prevent injury of-the coating by the-trembling or vibration of the conveyer, if such occur, as is apt to'be the case Where the conveyers are neglected or are of inferior design.

I claim and desire to secure the follow- In combination, an endless flexibleconveying device, a plurality of carriers-separable from and carried by the said conveying device, and a plurality of sharp supports upon each of the said carriers, the said sharp supports being located in cooperating positions adapted to jointly support Without penetration and at a plurality of points, an article resting lightly thereon, and means for rigidly securing, and releasing the'several carriers to and from the oogvelying device.

11 combination, an endless flexible con-- ve ing device, a plurality of carriers separa le from and carried by the said conveying device, and a plurality of sharp supports upon each of the said carriers, the said sharp supports being located in cooperating positions adapted to jointly support, without penetration and at a plurality ofpoints, an article resting lightly thereon and hearing simultaneously on the supports of a plurality of the carriers, and means for attaching and detaching the individual carriers.

3. In combination, an endless flexible conveying device, a plurality of sharp supports mounted thereon in positions to cotiperate in jointly supporting an article laid thereon, without penetration, at a plurality of points simultaneously, said supports ,hav- 1ng means for permitting their relative yielding and adjustment under the weight of the article.

4. In combination, an endless flexible conveying device, a plurality of sharp supports 5. In combination, an endless'fle'xible con-- veying device, a plurality of sharp sup ports mounted thereon in positions to co-' operate 1n ointly supporting an article laid thereon, without penetration, at a plurality of points simultaneously, some of the said supports embodying springs of a strength and automatic cooperative adjustment in ointly supportadapting them to a yiel ing such article.

6. In combinatlon, an endless flexible con veying device, a plurality of sharp supports mounted thereon in positions to cooperate in jointly supporting an article laid thereon,"

without penetration, at a plurality of oints simultaneously, disposed in substantia y thesame common plane, and. some of the said supports being yielding relative to the other cooperating supports under the weight of the article.

' 7. Aconveying device having a plurality of yielding and substantially sharp supports set in positions to coact jointly onthe' same article to be supported and adapted to adjust themselves relatively in bearing loosely on a plurality of points of a single article.
